Abstract Aim To investigate real‐world glycaemic outcomes and goals achieved by users of the MiniMed 780G advanced hybrid closed loop (AHCL) system aged younger older than 15 years with type 1 diabetes (T1D). Materials Methods Data uploaded from 27 August 2020 to 22 July 2021 were aggregated retrospectively analysed based on self‐reported age (≤15 >15 years) for three cohorts: (a) post‐AHCL initiation, (b) 6‐month longitudinal initiation (c) pre‐ versus initiation. Analyses included mean...

We studied real-world performance of MiniMed (MM) 780G system users from Argentina, Brazil, Colombia and Chile (geographical analysis), the effect each technology iteration MM on glycaemic control (technology analysis).CareLink data August 2020 to September 2022 were extracted. Endpoints included continuous glucose monitoring metrics. For geographical analysis, aggregated endpoints for MM780G calculated. user outcomes compared with when same individuals still using MM640G or MM670G system.On...

The concept of maintaining blood glucose levels within the 70-180 mg/dL range, known as time-in-range, has raised questions regarding its representation true physiological euglycemia. Some have speculated that focusing on time spent 70-140 introduced in tight range (TITR) through International Consensus statement, could serve a more precise metric for assessing normoglycemia individuals with type 1 diabetes. This article delves into current status TITR an emerging marker and explores how...

To evaluate the real-world performance of MiniMed 670G system in Europe, individuals with diabetes.Data uploaded from October 2018 to July 2020 by living Europe were aggregated and retrospectively analysed. The mean glucose management indicator (GMI), percentage time spent within (TIR), below (TBR) above (TAR) glycaemic ranges, use insulin consumed users 10 or more days sensor data after initial Auto Mode start determined. Another analysis based on suboptimally (GMI > 8.0%) well-controlled <...
